问题
Does anyone know what the method hasClients does in the android sdk?
boolean com.android.ddmlib.IDevice.hasClients()
It doesn't look like its documented.
I am trying to find a way to see if an emulator is being used. Any good way to do this?
for(int i =0; i < devices.length; i++){
if(!devices[i].hasClients()){
monkeyDevice = devices[i];
}
}
When I say is being used, I mean if there is currently an application running on the device or if its receiving commands from anything.
Update
I should of mentioned that I want to test for these conditions outside from my application. I have a seperate class running outside the application that starts the application within an available emulator. I want this monkey class to know if an existing emulator is already being used for testing.

Have a look at this question to figure out if you are running in the emulator:
How can I detect when an Android application is running in the emulator?
On a monkey-related point, you might want to have a look at Activity.isUserAMonkey() method (since API level 8, OS 2.2). The Google DeviceAdminSample code gives a brief explanation:
/**
* If the "user" is a monkey, post an alert and notify the caller. This prevents automated
* test frameworks from stumbling into annoying or dangerous operations.
*/
private static boolean alertIfMonkey(Context context, int stringId) {
if (ActivityManager.isUserAMonkey()) {
AlertDialog.Builder builder = new AlertDialog.Builder(context);
builder.setMessage(stringId);
builder.setPositiveButton(R.string.monkey_ok, null);
builder.show();
return true;
} else {
return false;
}
}
